| 作者于1982年秋对胶州湾潮间带海水中的水含量进行了调查。结果表明,胶州湾日益增加的工业排污虽然对沿岸海水水质影响不大,但对潮间带的水质影响较大,往往造成局部区间水质超标好几倍(如总汞含量最高者为1.830μg╱L),致使该区受到污染,因而必须引起高度重视。 |

| Abstract: |
| Seawater samples were collected from 15 stations in August, 1982 in the intertidal zone of Jiaozhou Bay where some primary plants discharge sewage. The contents of mercury in these samples were determined by cold vapour atomic fluorescence method. The results indicate that the range of total mercury contents are: 0.005-0.875 μg/L and 0.014-1.830 μg/L respectivity in the area studied. Total mercury contents in seawater are different considerably with stations. They were remarkably high at a few stations, yet exceeded the water quality standard by two or three times at others. The results showed that coastal industrial sewages have a greter influence upon seawater quality in intertidal zone. They raise the level of toxicant in some areas, the organisms living in these areas will consequently have a higher accumulation of toxicant. As a result this will do harm to the ecology in these environments. |
